چکیده

Importance of vibration problems increases with the smaller emittance of a storage ring for synchrotron radiation source. Vertical emittance of the SPring-8 storage ring is so small that effect of vibration to an electron beam can not be neglected. We thus studied the vibration of the SPring-8 storage ring. Measurements of beam oscillation and magnet vibration were done and the relation between them was investigated. Vibration source and propagation paths were also studied and the suppression method is discussed.

Estimation of Betatron Coupling and Vertical Dispersion for Spring-8 Storage Ring

The betatron coupling is one of the most important parameters of storage rings for high brilliant light source. By the precise alignment of the magnets [1] and the proper COD correction [2], the SPring-8 storage ring succeeded in achieving the very small linear betatron coupling without skew quadrupole corrector magnets. To prove this fact, we study the betatron coupling of the SPring-8 storage...

پایش لرزشهای بسامد بزرگ در اتاقهای آزمون موتور به کمک لرزهگیرهای بادی نیمه فعّال با پایشگر PID

Today there are different vibration isolators used in industries according to the weight and excitation frequency of the machines which have vibration. One of them is Air Spring which is in two types: Convoluted air spring and membrane air spring. Convoluted air springs are used to control vibrations in low frequency (usually lower than 10 Hz) and the membrane ones are used in high frequenc...

Suppression of Coherent Synchrotron Oscillation of the Spring-8 Storage Ring

For the realisation of a highly brilliant photon beam in a third generation synchrotron radiation source such as SPring-8, it is very important to eliminate an orbital vibration of the stored electron beam. In the SPring-8 storage ring, coherent synchrotron oscillation with amplitude of 0.2mmp-p was observed by BPM located in a dispersive section. Since the energy oscillation amplitude is propo...

Magnet Rearrangement for 30 m Long Straight Sections in the SPring-8 Storage Ring

In the summer of 2000, we constructed the four 30-m long straight sections in the SPring-8 Storage Ring. Magnets were rearranged to make long free spaces. New girders were designed, manufactured and installed to the SPring-8 storage ring tunnel. Magnets placed on the girders were aligned on a straight line using CCD camera and laser. A long undulator was installed in one long straight section a...
